Conceptis Slitherlink

Slitherlink are addictive loop-forming puzzles which were invented in Japan. Using pure logic and requiring no math to solve, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

Each puzzle consists of a rectangular lattice of dots with some clues in various places. The object is to connect the dots surrounding each clue so that the number of lines equals the value of the clue and the lines around all clues form one continuous loop with no crossings or branches. Empty squares may be surrounded by any number of lines.

The game features 2-finger tapping for quick zoom, auto complete clues setting and a link segment highlighting option to help to avoid creating separate loops.

For more fun, Conceptis Slitherlink includes a Weekly Bonus section providing an extra free puzzle each week.

All puzzles in this app are produced by Conceptis Ltd. - the leading supplier of logic puzzles to printed and electronic gaming media all over the world. On average, more than 20 million Conceptis puzzles are solved each day in newspapers, magazines, books and online as well as on smartphones and tablets across the world.

Fun, challenging (2.0)7/15/2014 7:03:00 AM4/5 By hiatusThey have different difficulty levels and lots of puzzles to do without paying. Controls could be easier (eg an eraser would be nice, and my finger often misclicks on the iPhone.)

Challenging fun (2.0)6/11/2014 4:35:00 PM4/5 By Licha257I love different types of logic puzzles and this one is definitely staying on my phone. My only complaint is that I wish it had an eraser (clicking each individual line segment to delete is frustrating when I really messed up). I love all the Conceptis games!
